10 Claims.

This invention relates to improvements in winding machines but particularly has for its object to devise a useful and novel apparatus for the uniform winding of artificial silk.

In the winding of threads into bobbin form it is desirable to achieve a cylindrical yarn body having tapered ends. It is also necessary in the winding of artificial threads which are freshly extruded through a coagulating bath, to wind these still plastic filaments under an almost uniform tension by insuring a smooth run of the thread, over a thread guide to which has been imparted a continuous movement.

It is therefore one object of the present invention to provide a useful and novel winding apparatus which builds up a thread body with tapered ends and whereby the outer windings form a protective layer.

Another object of the present invention is to provide a winding apparatus whereby the length of the taper of the beveled ends may be readily changed by means of a novel design of the eccentric means.

To the attainment of the aforesaid objects and ends, my invention consists in the novel features of construction and in the combination, connection and arrangement of parts, hereinafter more fully described and then pointed out in the appended claims.

In the drawings:

Fig. 1 is a side elevation of my improved winding device, parts being shown in section and only so much of a spinning machine as is necessary to illustrate my device.

Fig. 2 is a Vertical cross-section taken on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged detail view of my adjustable cam means shown in the position which will impart the greatest arc of movement to the thread guide on the carrier bar.

Fig. 4 is an enlarged detail view of the parts shown in Fig. 3 with the eccentric shown at the other extreme of adjustment, whereby no relative movement will take place between thread guide and carrier bar.

In the drawings in which like numerals of reference indicate like parts, I refers to the frame of the spinning machine which supports the windlng apparatus comprising the invention.

A pair of drive shafts 2-2 run lengthwise of the spinning machine and drive cross shafts 3 through the medium of gears 4 and 5.

'Ihe cross shafts 3 are mounted in bearing 6 of the frames I. Mounted on the shafts 3 and 1934, Serial No. 714,976

rotating therewith are the spool holders I on which are mounted the winding spools 8.

Associated with the spools 8 are thread guides 9. In order to obtain a cylindrical body of thread, the thread guide is reciprocated longitudinally 5 across the surface of the spool as the latter roates.

The thread guides 9 are secured to arms 9a pivotally mounted on a carrier bar I0 which slides over rollers II mounted in brackets I2. This carrier bar I0 has rigidly mounted thereon a gear casing I3, of which more will be said later. A bracket I4 connects the casing I3 with a rack I5 which is engaged by a pinion I6 keyed on a shaft II which is mounted in a protective casing I8. The shaft II and pinion I6 are oscillated by another pinion I9 engaged by a rack 20 carrying a follower roller 2I which moves in a heartshaped cam track 22 of the cam 23.

The cam 23 is mounted on and driven by a drive 20 shaft 24 and it is thus readily perceived how the carrier bar I0 is reciprocated by this cam driven rack mechanism. The apparatus so far described imparts uniform stroke lengths to the thread guide.

'Ihe thread guide arms 9a are mounted on the pivotal shafts 25 carried by the carrier bar I0 and adapted to pivot with the said shafts 25. The thread guides 9 and shafts 25 are oscillated through the medium of a crank arm 26 rigidly 30 mounted on the shaft 25 which is link connected at 21 to an eccentric stud 28. The stud 28 is mounted on a collar 29 which is held in position on a second stud 3D by means of a set screw 3|. This second stud 30 is also eccentrically mounted 35 and is adapted to be rotated by a shaft 32.

The eccentric drive means comprises a drive shaft 33 which drives a shaft 34 through gears 35 and 36. The driven shaft 34 extends into and through bearings 3l in the gear casing I3 40 and bears a slidable relation thereto.

A bevel gear 38 is slidably mounted on the sh-aft 34 and within the casing I3. Keys 39 are mounted in said gear 38 and extend into slots 4B of the shaft 34 so that the gear 38 may be re- 45 ciprocated along said shaft and yet be rotated thereby.

The gear 38 meshes with another bevel gear 4I within the casing I3, which gear 4I is mounted on the shaft 32 and rotates the said shaft, which 50 shaft carries the eccentric stud 30 on the enlarged shaft end 42.

The pivotal shafts 25 on either side of the spinning machine are adapted to operate in unison. One means of doing this is illustrated in 55 Figure 1 of the drawings Where crank arms 43 are rigidly mounted on said shafts and connected by a lever 44.

In order to easily and accurately adjust the swing of the thread guides 9 a novel crank arrangement is used which is disclosed in detail in Figures 3 and 4 of the drawings.

Figure 3 discloses the eccentric means adjusted to give the greatest oscillating arc, whereas Figure 4 shows the eccentric means so positioned that no oscillation will take place. By merely loosening the set screw 3l, the eccentric collar 29 may be turned on the stud 3D to the desired position decreasing or increasing the distance of stud 28 from the center of rotation of the shaft 32 and so gauging the arc .of oscillation of the thread guide 9 within very accurate and well defined limits.

In operation the thread guides 9 are reciprocated longitudinally past the faces of the spools 8 by the reciprocating bar l0 and further movement is given to the thread guides 9 by the eccentric mechanism mounted on the said carrier bar Ill.

In Figure 1, in full lines, the thread guides 9 are shown at the center of the spools 8. The dotted line positions show the thread guides 9 at the limit of their pivotal swing in one direction and is indicated at the end of the stroke of the carrier bar I0 in both directions. Dot and dash lines illustrate the opposite of the pivotal positions of the thread guides 9.

In Figure 1 of the drawings, the yarn bodies are outlined in dotted lines on the spools 8. The central or cylindrical portion of the yarn body is designated by the numeral 45 and the beveled ends are indicated at 46. It will be noted that thread is always being received at the central portion thereby building the cylindrical part of the yarn body, because more thread is layed thereon. The extreme ends of the yarn body only receive the thread when the thread guides are at the extreme end of their pivotal arc simultaneously with the extreme end position of the reciprocatory movement of the carrier bar I0, which position least occurs of any of the intermediate positions. In this manner it is readily seen how the beveled ends of the yarn body are built up.

From the foregoing description, taken in connection with the accompanying drawings it is thought the complete construction, operation and advantages of my invention will be clearly apparent to those skilled in the art.
